The LA-based artist Jennifer West came to Tate Modern to create a new film live in the gallery. Instead of cameras, her process involves manipulating and making marks on the celluloid film itself. For this performance ink-covered film strips were laid out along the ramp of Tate Modern’s turbine hall. A team of skateboarders then traversed the slope, their wheels scraping marks into the celluloid. West then spent the rest of the night splicing the film together, ready to showcase the psychedelic patterns created by the skaters’ movements. http://www.tate.org.uk/modern/eventseducation/musicperform/18340.htm
